IMPROVEMENT IN CONSTRUCTION OF WALLS.

Specification forming part of Letters Patent No. 166,760, dated August17, 1875; application filed June 25, 1873.

To all whom it may concern:

Be it known that I, GRANVILLE H. FIELD, of Auburn, in the county ofAndroscoggin and State of Maine, have invented certain new and usefulImprovements in the Walls of Buildings; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, that willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

My invention relates to certain improvements in the walls of buildings,by which I am enabled to employ an artificial-stone compound. By thisterm I mean cement, mastic,

or an like lastic material or com osition used for facing the outside ofhouses, or their inside walls, ceilings, 860. The outer face can beformed or marked to imitate stone or any other desired description ofouter walls.

The invention consists more particularly in constructing a wall forbuildings by means of cross-pieces and uprights made of wood, andsuitably prepared by being immersed in or coated with tar or some likesubstance, and in the application and adjustment of the same each to theother, so that suitable spaces of desirable shape shall be left betweenthem, and the surface or face so made covered with any desired compound,as above, all as will now be more specifically and in detail set out.

In the accompanying drawing, a represents an upright or joist of abuilding. These uprights are made of wood. Across these are stretchedthe horizontal laths or pieces I). 0

indicates the compound when applied to the outside. It will be observedthat the pieces I) are made flaring, or of that form called dovetail;but any suitable form may be used. The compound 0 is of course appliedwhen in a green or plastic state. Being pressed and tting into thespaces between the stretchers b, it is, when dried, held securely to itsplace on the wood-work of the building.

The chief danger to be avoided in this kind of wall is the cracking ofthe compound a by reason of the contraction and expansion of the piecesb as they are afi'ected by the heat or dryness or moisture of theatmosphere. This I prevent by coating or soaking the parts I), and, ifrequired, a, in tar or any resinous, bituminous, or tarry compound,which will prevent the wood from being affected by heat or cold, andprevent the absorption of moisture.

When thus prepared the frame-work, composed of the parts a and b, isfirst set up, and then the coating 0 is filled in, beginning from theouter edges of the uprights a. Of course, if desired, it can penetratebetween them; but, in practice, it will be found sufficient to commencewith the compound at the line (I. The compound can have such thicknessover the stretchers, on the outside, as experience shall determine. Theboarding, if desired, can be laid between the stretchers b from oneupright to another, to fill up the bottom or inner end of the spacesbetween the stretchers, and for the compound to rest against.

A Wall thus constructed will successfully resist theinfluences ofweather,'is strong, warm, and capable of being with ease worked intoornamental designs on the outside. It is cheap, and can be built withrapidity.

If desired, these walls. can be built in portable sections.

What I claim as my invention, and desire Witnesses:
